Castle of Castellet Monument · Castellet i la Gornal, Alt Penedès, Barcelona The castle of Castellet stands in the Foix natural park, halfway between Barcelona and Tarragona, in the Alt Penedès comarca, and is today the seat of the Fundació Abertis. It was built in the year 977 to defend the Marca Hispanica, first as a simple domicilium with a watchtower and a small wall, extended between the 11th and 12th centuries -the 12th-century keep, about 15 metres high, is the oldest surviving element-; its strategic position made it grow in power, passing through the hands of 44 owners, among them the Santmartí, the Castellet, the Requesens and finally the counts of Queralt, until the abolition of feudal lordships in 1837. It was rebuilt in 1928-1929 by the architect Josep de Peray i March, and today houses rooms that the foundation makes available for presentations, seminars and conventions.
